4.8 Operating Tips
• When an analyzer s brought n from a cold vehcle, let t warm up
slowly to mnmze condensaton. Temperatures below freezng wll not
damage the analyzer; however, brngng a cold analyzer nto a warm,
humd envronment may cause condensate to form nsde the case.
• If the CO channel s set up for Auto Zero (refer to Secton 3.4.3), en-
sure that the analyzer s samplng fresh ar when turned ON. Pullng
a flue-gas sample through the analyzer during its warm-up period will
not damage the analyzer, but t wll result n ncorrect CO readngs.
Also note that a CO sensor error wll occur f the detected CO level s
above 50 ppm during warm-up.
• Flue-gas condensate is acidic and very corrosive. It is important not to
allow the analyzer’s nternal components to become soaked n conden-
sate for long perods of tme.
• Before each use, inspect the filter element of the water-trap / filter as-
sembly. Replace the filter if it looks dirty.
• During a test, keep the analyzer above the water-trap, and keep the trap
n a vertcal poston. Ths wll maxmze the effectveness of the trap
and keep lqud condensate from beng drawn drectly nto the analyzer.
• When lqud condensate s seen nsde the water trap, empty the trap
before t becomes full. Refer to Secton 5.4.
• It is recommended that the analyzer be purged after taking a flue-gas
measurement before turnng t OFF. Once the probe s removed from the
stack, dsconnect the hose assembly from the bottom of the analyzer and
let the pump run for 10 mnutes or so to completely remove any reman-
ing flue gases, and dry any condensate from inside the sensor chamber.
• When storng the analyzer, t’s a good dea to empty the water trap and
leave t open to further dry t out.
• Calbrate the analyzer about every 6 months to ensure ts accuracy.
4.9 Resetting the Microprocessor
If the analyzer ‘locks up’ and cannot be turned OFF, reset the mcroproces-
sor by removng one of the batteres for 5 seconds.
